Error 14 can be a hardware error, and error 2003 does not appear, but ones in that number range are USB connection errrors.

Try disabling your anti-virus software and/or firewall. Can you check the speed of your internet connection. It sounds like it may be slow as well.

My broadband connection to my cable provider is fiber optic as well, but it can slow to a crawl sometimes. Generally unplugging the modem for a couple of minutes and then starting it back up can fix that, but don't have false hope that it is always fast.

However, back to your issue, can you try another computer?

Again, from the link I provided you earlier, it could be a USB error. If you follow all of the steps in the USB section, it says to try the hardware section, an if that doesn't work, then contact Apple Support.

Check your USB connections

Related errors: 13, 14, 1600, 1601, 1602, 1603, 1604, 1611, 1643-1650, 2000, 2001, 2002, 2005, 2006, 2009, 4005, 4013, 4014, or "invalid response."

If the USB connection between your device and computer is interrupted, you might not be able to update or restore.

To narrow down the issue, you can try different equipment:

• Use the USB cable that came with your device, or a different Apple USB cable.
• Plug your cable into a different USB port directly on your computer. Don't plug it into your keyboard.
• Try a different computer.
• Solve other issues with the USB connection, then with your security software.

If you still see the error message, check for hardware issues by following the next section.

Check for hardware issues

Related errors: 1, 3, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.These errors mean that your device or computer might have a hardware issue that stops the update or restore from completing.

1. Check that your security software and settings aren't blocking your device from communicating with the Apple update server.
2. Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
3. Make sure that your security software and settings are allowing communication between your device and update servers.
4. If you still see the error message when you update or restore, contact Apple support.

I realize there is no exact description for the error 2003, however it is in the range indicated for USB errors. I suggest you just take the time to make a Genius Bar appointment for the device since it is not going to restore. There is nothing that anyone else can recommend here, since you have tried all of the steps.
